Subsurface Radar
Wednesday, 13 June, 2001
An Australian subsurface radar can detect hidden objects that cannot be found by other means. "The radar unit is able to look with high resolution close to the surface," says CSIRO researcher, Dr Tony Farmer. The SSR is able to find a wide range of both metal and non-metal objects.
It works by transmitting high frequency pulses through the background medium and detecting echoes reflected either by objects buried within the material, or from interfaces between different media types.
The timing and spatial location of the echoes provides information about the subsurface objects or layers.
The radar control unit is connected to a notebook computer and data acquisition and processing is provided by an appropriate software package.
